APPARATUS FOR TRANSFERRIING o -zrmm-zo SCRAPS.

SPECIFICATION forming part of Letters Patent No. 737,117, dated August 2 5, 1903.

Application filed Novcm'ber25, 1902. Serial No. 132,719. (No model.)

To all whom itmcty concern:

Be it known that we, MARTIN LAERNOES, a citizen of the Kingdom of the Netherlands, and JOHN DUNN,a citizen of the United States 5 of America, both residing in Streator, in the county of Lasalle and State of Illinois, have' invented certain new and useful Improve-. ments in Apparatus for Transferring De-- tinned Scraps, of which the following is a specification.

This invention relates to an improved apparatus for transferring detinned scraps by taking the same from the trucks coming from the detinning-vats into the washing-tank and I 5 removing thereby the adhering detinning solution, the apparatus permittingv the trans-. ferring and lowering of any number of bets-- kets in a group and in vertical'position, so

as to facilitate thereby the handling of the baskets and produce considerable saving of time in placing them intothe washing-tanks and transferringthem from the same again to the trucks; and for this purpose the invention consists of an apparatus for transferring z 5 detinned tin-scraps which comprises a movable carriage supported on ways, a. suspen-v sion-bar provided with a number of books.

each adapted to engage the bails or handles of two adjacent baskets at the same time,

means for counterbalancing said suspensionbar and basket for lifting or lowering the same into the tanks, transferring the same to the truck, and vice versa.

The invention consists, further, of the spe-;

cialconstruction of the suspension-bar and.

hooks for taking hold of a pluralityof baskets at the same time and handling them for submerging in the washing-tank or placing on the trucks, as the case may be, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of the improved apparatus for transferring detinned scraps,

showing the basket inposition on the truck before being transferred into the washingtank. Fig. 2 is a similar elevation showing the baskets transferred by the improved apparatus into the washing-tank. Fig. 3 is a plan View ofFig. 1. Fig. 4 is a vertical trans- 5o verse section on line 4: 4, Fig. 1, drawn on a larger scaleg'and Fig. 5 is a perspective view of the suspension-bar with its basket-holding hooks.

Similar letters of reference indicate corresponding parts. v

Referring to drawings,'A represents a suspension-bar which is made of iron or steel of sufiicient thickness and provided with a number of hooks-a, the flattened shanks of which are attached thereto by rivets or otherwise and which extend in forward direction at right angles to the bar, being bent in such shape that each hook readily engages the supportin handles or bails of two adjacent detinning-baskets, such as are employed in the process of detinning tin scraps or clippings by the electrolytic process. The suspensionbarA is suspended, by means of straps S, from a sheave or pulley B, over which is placed a wire rope C, said wire rope being conducted over sheaves dof a carriage D, which is moved in horizontal waysE, that are supported in suitable posts, brackets, hangers, or otherwise in proper relative position to the trucks and tanks over which the baskets are to be transferred. One end of the wire rope is connected with a weighted plunger. The plunger is guided in a hydraulic, steam, or aincylinder F, to which the pressure medium is ad- 8:

mitted by a suitable valve-gear operated by the attendant. The opposite end of the wire rope is attached .to a stationary point or abutment L on the end of the guideways E for the carriagel). The frame of the carriage Dis provided with inclined downwardly-extending handles D; which are arranged symmetrically and at opposite sides of the suspension-bar A and sheaves B, said handles serving for the purpose of moving the carriage, 0 with the suspension-bar and baskets suspended therefrom, from the truckto the tank, then from the tank to the transferring-truck after the'washing operation has been completed. The track for the transferring-truck T runs 5 alongside all the washing-tanks, only one of which, V, is shown in the drawings, in connection with similar transferring apparatus, extending above and across all tanks in the same manner as the transferring apparatus in Fig. 2 extends across the washing-tank. A plurality of baskets, preferably eight, containing the detinned scraps is submerged in the tank, so as to clean the detinned scraps from all adhering solution after the process of detinningis completed. The eight baskets are simultaneously taken hold of and transferred from the trucks by the hooks of the suspension-bar A, each hook engaging the supporting handles or bails of two adjacent baskets G, as shown in Fig. 1, which being taken hold of at one side of their center of gravity are suspended vertically adjacent to each other from the suspension-hooks of said bar, as shown in Fig. 4- 'Ihus lifted by the suspension hooks they are transferred, by means of the carriage and ways, into position vertically above the washing-tank and then lowered, so as to be submerged in the same. By the dipping or submerging of the baskets with the scrap into the tank the adhering solution is removed from the same, after which the baskets are lifted again by reversing the valve-gear of the hydraulic, air, or steam operating cylinder by the attendant, so that the baskets are lifted out of the tank and returned again by taking hold of the handles back to the truck-platform, which then conveys the baskets with the scraps to the place where the scraps are compressed into blocks ready for being returned to the mill for being melted.

By the apparatus described a plurality of pairs of baskets can be simultaneously transferred from the trucks to the washing-tanks and from the washingtanks to the place where the scraps are removed from the baskets for being compressed, the transferring apparatus having the advantage that the baskets are always suspended bytheir own gravity in vertical position, so that the handling of single baskets is dispensed with and considerable time and labor in transferring and washing the scraps is saved.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. An apparatus for transferring detinned scraps, which consists of stationary guideways, a carriage provided with handles supported on the same, sheaves on said carriage, a wire rope passing over said sheaves, a guidesheave suspended on said rope between the sheaves of the carriage, a suspension-bar carried by said guide-sheave, a plurality of hooks attached to said bar, said hooks being adapted to engage the adjacent bails of a plurality of baskets containing detinned scraps, and means for raising-or lowering the suspensionbar, substantially as set forth.

2. An apparatus for transferring detinned scraps, consisting of stationary horizontal guideways, a carriage provided with sheaves moving on said guideways, handles extending downwardly from said carriage, a wire rope attached to a stationary point at one end and passing over the sheaves of the carriage, a guide-sheave on said rope between the sheaves of the carriage, a suspension-bar located on the guide-sheave, said bar being provided with a plurality of hooks for engaging the bails of the scrap-containing baskets, and means connected with the opposite end of the wire rope for raising or lowering said suspension-bar, substantially as set forth.

3. In an apparatus for transferring detinning-baskets, a suspension-bar provided with a plurality of forwardly-extending hooks having flattened shanks attached to said bar and extending at right angles to the bar so that each hook is adapted to engage the bails of two adjacent baskets at the same time, substantially as set forth.

In testimony that we claim the foregoing as our invention We have signed our names in presence of two subscribing witnesses.
